Abstract

Titre : Ventilateur d’une machine électrique tournante. La présente invention a pour principal objet un ventilateur (16) d’une machine électrique tournante (1) composée d’au moins un stator (4) et d’un rotor (10) configuré pour être entraîné en rotation autour d’un axe de rotation (R), le ventilateur (16) étant destiné à être monté sur une extrémité axiale du rotor (10) et entraîné en rotation autour de l’axe de rotation (R), le ventilateur (16) comprenant une base (24) et une pluralité de pales (26) faisant saillie de la base (24), la pluralité de pales (26) étant configurée pour guider un premier flux d’air radialement par rapport au ventilateur (16), le ventilateur (16) comprenant une pluralité d’interpales (30) faisant saillie de la base (24) configurée pour guider au moins en partie un deuxième flux d’air axialement par rapport au ventilateur (16). Figure 3.Title: Fan of a rotating electric machine. The main object of the present invention is a fan (16) of a rotating electrical machine (1) composed of at least one stator (4) and a rotor (10) configured to be driven in rotation around an axis of rotation (R), the fan (16) being intended to be mounted on an axial end of the rotor (10) and rotated around the axis of rotation (R), the fan (16) comprising a base (24 ) and a plurality of blades (26) projecting from the base (24), the plurality of blades (26) being configured to guide a first air flow radially relative to the fan (16), the fan (16) comprising a plurality of interblades (30) projecting from the base (24) configured to guide at least in part a second air flow axially relative to the fan (16). Figure 3.
